Serial No. 617,884.

To all. whom it may concern:

Be it known that I, GEORGE T. BAILEY, a citizen of the United States, residing at- Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and useful Attachment for Cooling and Vending Machines, of which the following is a specification.

My invention relates to improvements in attachments for cooling and vending machines in which .a coin is guided into a notch in an otherwise freely moving cylinder so as to engage pins connected with the discharging appliances of thedevice proper so as to secure the otherwise movable and free cylinder with the discharging and reloading device so as to operate it by means and the objects of my invention are, first, to provide means for bringing. forth from a magazine or receptacle the desired articles therein one at a time; second, to provide means for automatically opening and closing said magazine or receptacle atthe time desired in the transmission of the article. I attain these objects by means of the mechanism illustrated in the accompanying drawin s, in which- 1 igure 1, is a vertical section of Fig. 2, on" the l1ne.AB; Fig. 2, a top view of the device with cover removed and coin inplace on cylinder; Fig.3, a vertical section of the right side of Fig. 4, on the line C-D; Fig. 4, a top view of the device showing cover removed and @in released and taken; Fig. 5, a front elevation of two of 13118335- tachments united with one lever for operation; Fig. 6, a perspective of the packa e automatic obstructing shutter; Fig.. 8, a perspective of the automatic outlet door; Fig. 9, a side elevation of the check lever 11', in friction contact with the -V grip 12, enclaspin'g the check pin 13.

Similar letters and figures refer to similar parts throu bout the several views.

The driving shaft 3, carrying one or more cylindrical coindrums 4, the obstruct.- ing shutter 29, the outlet door 35, the delivering elevator 41, together with the package and means for operating these four parts in harmony, constitute the principal parts of my device. The; driving shaft 3, extends through the body of one or more of the casmgs of the devices and is operated by a single crank lever 2, having the handle knob 1. Rigidly secured to the driving shaft 3, near one side of the receptacle is the coin drum 4, having in its perimeter the coin slot 15, showing in- Fig. 1, the coin 8, in place ready to engage the driving pin 9.

Patented Feb. 6,1912.

Loosely mounted on the driving shaft 3.

is the hollow sprocket shaft 5, carrying the two sprocket wheels 7, one of which is rigidly secured to either end and each carrying one of the sprocket chains, the front end 14, of each chain being secured to the top of the right and left ends 19, 19 of the elevator and herein designated the elevator chains, while the rear ends 6, of the sprocket chains are designated the shutter chains and are secured-to the lifting levers 31, provided to elevate and lower the upright arms 30, at the lower endof which is secured the obstructing shutter 29. Attached intermediatethe ends of the lifting levers 31, are the depression springs 40, arranged to force down the said levers 31, and the obstructing-shutter 29, when released from the tension of the shutter chains 6. The package chute 28, is an inclined magazine provided to hold packages to be-delivered to the. package elevator 41, shown in Fig.6, Fig. 1, and Fig. 3.

I In Fig. 1, is shown the elevator41, in the bottom of the elevator shaft, with part of the walls 23, of. the shaft removed so as to disclose the partswithin it. Here the package 25, is shown in the'elevat'o'r having just dropped past under the obstructing shutter 29, and is ready to be raised up the elevator shaft to the outlet door 35. In the sides of the elevator shaft are guide rods 22, provided to be-received by the guide grooves 20, in the ends 19, of the elevator. 1

To obtain the package 25, in elevator, the operator places the required coin 8, into the intake 34, of the coindelivering chute 33, as shown in Fig. 2, and Fig. '4, whence it is conveyed-by gravitation to the coin slot 4 15, in drum 4, as shown in Fig.1 where it is projecting in the path of' the driving pin 9, which 1s rigidly attached to sprocket wheel 7, and is shown in this view between the coin 8, and the driving pin 10, rigidly attached .to coin drum 4, thus securing the sprocket wheels 7, so as to be turned with the crank lever 2, by means of .handle knob 1. The operator now turns the handle knob 1, downwardly and this pulls up onthe elevator chains 14,. which aresecured to theends 19, 19, of the elevator 41, which lifts it to the position at the top of the elevator shaft as shown in Fig. 3, allowing the package, to roll out upon the delivery tray 42. As the elevator 41, begins to rise the obstructing shutter 29, is forced down and closes the entrance to thebottom of the elevator shaft from the chute 28, and prevents the package 27 as shown in Fig. 3, from entering the elevator shaft until the elevator 41, has been returned to the bottom of the shaft as shown in Fig; 1. The coin 8, secured in the coin slot 15, in the drum 4, engages the driving pin 9, and with it forces the rotation of the sprocket wheels 7, which rot-ate together on the driving shaft 3, by means of the hollow sprocket shaft 5, as shown in Fig. 2, and Fig. 4.

On the shaft 5, at its end opposite the crank lever 2, is rigidly attached the check lever 11, at one end and projecting at right angles therewith, as shown in Fig. 2, and Fig. 4. In shown projecting forward while the cranklever 2, is shown projecting backward,- and they both being rigidly secured by the coin 8, maintain the same relative positiontoward each other. In the outer side of the check lever 11, and near its swing end is the check pin 13, provided to be received and held by the V grip 12, as shown in Fig. 9, on an .enlarged scale, or detail. The prongs of this V grip are of elastic material and have a tendency to hold the check pin 13, by friction. 'When the elevator 41, is raised to the top of the elevator shaft the check pin 13, is forced into the grip of the V grip 12, and is held so tightly that it requires considerable reverse force on the handle knob 1, to release it, additional to the weight of the elevator. While the elevator is being raised, the coin 8, is firmly held in place in the coin slot 15, by the pressure of the driving pin 9, being forced against it by the weight of the elevator and its contents, and though the coin slot 15, shouldbe turned downwardly as shown in Fig. 3, the coin would not be released from the drum 4,

while being pressed against by the driving pin 9, caused by the weight of the elevator. When the check pin 13, is forced into the V grip 12, it is held therewith sufficient friction to overcome the weight of the elevator 41, and as the check lever 11, is rigidly and permanently secured to the hollow sprocket shaft 5,v and turns therewith it holds the elevator 41, from dropping down and holds the sprocket wheels 7, from turning to the left on top until forced back by the crank lever Fig. 2, the check lever 11, is-

2, forcing the vdriving'pin 10, against the driving pin 9, which releases the pressure of the driving pin 9, on the coin 8, and allows it to drop down and out of the coin slot 15, and then the force of the pressure of driving pin 10, against driving pin 9, will force the check pin 13, from between the prongs of the V grip 12, and allow the machinery shown in Fig. 3, to be turned back to assume the position shown in Fig. 1, thus lifting the obstructing shutter 29, so as to allow the cylindrical package 26, to roll down into the elevator and occupy the position shown in .Fig. 1, by package 25.

The liftlng levers 31, are pivoted at 32,'

their rear end, and drop downwardly as the elevator is raised upwardly, until the 0bstructing shutter '29, is arrested by coming into contact with a package, as 26, shown in Fig. 1, or into contact with the bottom of the package chute 28, after which the shutter chains 6, will fold slack as shown in Fig. 3, because of the fact that the elevator 41, has a longer course to traverse than has the obshtructing shutter 29, as shown in Fig. 1 and The outlet door 35, is suspended pivotally at its two upper corners and hangs downwardly and closes partly by gravitation and by the force applied to the door lever 36,

which projects upwardly from the edge of the door and is actuated by the door pitman 27, attached to the crank wrist 38, secured into the side of the sprocket wheel 7, as shownin Figs. 1-2-34. In Fig. 8, is shown a detail in perspective of the outlet door 35, and its bearings 44, upon which it is pivoted, and the pivot connection 39, between the top end of outlet lever 36, and the front end of door pitman 37. As the handleknob 1, is turned backwardly and u wardly from the position shown in Fig. 3 to t e position as shown in Fig. 1, the door pitman 37, forces the outlet door 35, closed and prevents access of thehumanhand or of vermin or dust or other obnoxious subjects. The orifice 45, provided for the outlet for the packages 24- 2526 and 27, is shown open in Fig. 3, and closed in Fig. 1, by-the outlet door 35.

In Fig. 5, is shown the front of my appliance showin the cabinet with two compartments joine together, or with two of my appliances inclosed in a double cabinet, provided to be operated by the single lever 2, and the continuous extension of the shaft 3,

projectingthrough the double cabinet. This,

vator in a cabinet containing a plurality of these appliances described, to be raised by connecting its. mechanism with the driving shaft 3, by means of the proper coin being dropped into the proper slot 34. This ap-. pliance is provided to' have arrangement for different sized coins for different machines for different, sized slots and different priced packages. In this Fig. 5, the outlet door 35, to the right is shown open disclosing the outlet orifice 45, and the left side shows the outlet door 35, closed as shown in Fig. 1.

The floor 17, of the elevator slopes outwardly toward the front of my appliance so that when the elevator is raisedto the top .of the shaft, as shown in Fig. 3, the package ,24, will roll forwardly out of the elevator and down into the delivery tray 42, as shown in Fig. 8. As the bottom of the elevator shaft will sometimes contain water for cooling the packages, as 25, and 26, I have provided perforations 21, in the floor of the elevator to allow any liquid to drain through it and soas to not spill any liquid upon the delivery tray 42.

I am aware that prior to my invention coin vending attachments have been used for various purposes of selling and dispensing small articles or packages on various kinds of magazines of supply by means of attaching and detaching a crank to the machinery proper by means of a coin. I therefore do not claim such a combination broadly; but v I claim:
